Question 1Question

In a manufacturing firm producing leather footwear, various expenses are incurred during the production process. Which of the following costs is classified as a direct expense and included in the calculation of Prime Cost?

Show answer & explanation

Answer: Royalties paid to a designer based on the specific number of units produced

Answer

Royalties paid to a designer based on the specific number of units produced
Royalties paid per unit produced are direct expenses because they can be traced completely to individual manufactured items. Adding direct expenses to direct materials and direct labor gives Prime Cost.

Step-by-Step Solution

1
Understand the components of Prime Cost
Prime Cost consists of direct materials, direct labor, and direct expenses.
Prime Cost includes all expenditure directly traceable to the physical unit of production.
2
Identify the nature of direct expenses
Direct expenses are expenses other than direct materials and direct labor incurred specifically for a particular product or batch (e.g., royalties paid per unit produced or specialized equipment hire).
Royalties paid on a per-unit basis can be directly attributed to each item manufactured.
3
Differentiate direct expenses from indirect manufacturing overheads and non-manufacturing costs
Factory supervisor salary is indirect labor (factory overhead); carriage outwards is a selling expense; machinery purchase is capital expenditure.
Only royalties paid per unit manufactured meet the strict definition of direct expenses.

Question 2Question

A commercial publishing firm producing custom-designed academic textbooks incurred the following expenditures during a financial period:

I. Copyright royalties paid per copy to book authors
II. Cost of paper and printing ink used in production
III. Rental fees for specialized binding machinery hired exclusively for a specific job
IV. Salary of the factory maintenance engineer

Which combination of items strictly represents direct expenses in the calculation of Prime Cost?

Show answer & explanation

Answer: Copyright royalties paid per copy to book authors and rental fees for specialized binding machinery hired exclusively for a specific job

Answer

Copyright royalties paid per copy to book authors and rental fees for specialized binding machinery hired exclusively for a specific job.
Direct expenses are costs specifically incurred for a particular job or product line, apart from direct materials and direct labour. Copyright royalties paid per copy to authors and rental fees for specialized machinery hired exclusively for a specific contract are directly traceable to specific production runs and are therefore classified as direct expenses.

Step-by-Step Solution

1
Define Prime Cost and its components
Prime Cost consists of Direct Materials + Direct Labour + Direct Expenses.
Understanding the components of Prime Cost is essential for proper cost classification in manufacturing accounts.
2
Identify the definition of Direct Expenses
Direct expenses are expenditures incurred directly and exclusively for a specific product, job, or batch, other than raw materials and direct labour.
This isolates direct expenses from direct materials, direct labour, and indirect factory overheads.
3
Classify each given cost item
Item I (Author Royalties) = Direct Expense; Item II (Paper and Ink) = Direct Material; Item III (Special Machinery Hire for a Specific Job) = Direct Expense; Item IV (Factory Maintenance Engineer Salary) = Factory Overhead (Indirect Labour).
Evaluating each item against cost classification definitions allows accurate categorization.
4
Select the combination consisting strictly of Direct Expenses
Items I and III constitute direct expenses.
Only author royalties and job-specific machinery rental represent direct expenses.

Question 3Question

In the operations of a commercial bakery, raw flour and sugar are directly converted into finished loaves of bread. Which of the following expenditure items constitutes a direct cost that forms part of prime cost?

Show answer & explanation

Answer: Cost of raw flour and baking ingredients consumed

Answer

Cost of raw flour and baking ingredients consumed
Prime cost is the sum of direct materials, direct labor, and direct expenses. The cost of raw flour and baking ingredients represents direct raw materials directly traceable to the manufactured loaves of bread.

Step-by-Step Solution

1
Identify the total direct costs involved in the production process.
Prime cost consists of Direct Materials + Direct Labor + Direct Expenses.
Prime cost represents all expenses directly traceable to the physical creation of the finished unit.
2
Classify raw flour and baking ingredients.
Raw flour forms the basic direct material input of bread.
It forms a direct part of the manufactured product and is therefore classified under direct material cost.

Factory Overheads
Work-in-Progress
Cost of Production

Matches

Show answer & explanation

Answer

Prime Cost matches with the aggregate total of direct materials, direct labour, and direct expenses. Factory Overheads matches with the sum of all indirect factory production expenses. Work-in-Progress matches with partially completed goods remaining in the factory at period end. Cost of Production matches with the net total cost of completed goods transferred to the Trading Account.
Each manufacturing term is accurately matched with its accounting definition: Prime Cost is the sum of all direct expenses; Factory Overheads represents all indirect production expenses; Work-in-Progress refers to uncompleted inventory at period end; and Cost of Production is the net cost of finished goods transferred to the Trading Account.

Step-by-Step Solution

1
Identify the primary direct components of production cost.
Prime Cost is the sum of Direct Material + Direct Labour + Direct Expenses.
Direct expenses are costs specifically traced and assigned directly to units produced.
2
Identify the indirect operational costs within the factory.
Factory Overheads comprise indirect material, indirect labour (e.g., supervisor salary), and indirect expenses (e.g., factory rent, machinery depreciation).
Costs incurred inside the factory that cannot be traced directly to a single unit are treated as factory overheads.
3
Evaluate uncompleted inventory at the closing date.
Work-in-Progress (WIP) represents goods partially processed but not yet finished.
Adjusting for opening and closing WIP ensures that costs allocated strictly match goods completed in the current period.
4
Determine the overall balance transferred out of the Manufacturing Account.
Cost of Production = Prime Cost + Factory Overheads + Opening WIP - Closing WIP.
This total reflects the cost to bring finished goods into stock and is transferred to the Trading Account.

Question 5Question

A bespoke furniture manufacturing firm in Lagos provided the following extract from its financial records for the year ended 31st December 2025:

Accounting ItemAmount ()
Opening stock of raw timber60,000
Purchases of raw timber450,000
Carriage inwards on raw timber30,000
Direct wages paid to craftsmen280,000
Royalty on furniture designs40,000
Salary of factory supervisor120,000
Factory rent and rates90,000
Closing stock of raw timber50,000

Based on the information above, calculate the Prime Cost of production for the year in Naira.

Show answer & explanation

Answer: 810000

Answer

The Prime Cost of production for the year is 810,000₦810,000.
The correct answer of 810,000₦810,000 is obtained by adding the Cost of Raw Materials Consumed (490,000₦490,000), Direct Labour (280,000₦280,000), and Direct Expenses (40,000₦40,000). Indirect factory costs such as supervisor salary (120,000₦120,000) and factory rent (90,000₦90,000) are excluded because Prime Cost consists exclusively of direct costs.

Step-by-Step Solution

1
Calculate Cost of Raw Materials Consumed
490,000₦490,000
Cost of Raw Materials Consumed is determined by adding carriage inwards to purchases of raw timber and opening stock, then deducting closing stock of raw timber: 60,000+450,000+30,00050,000=490,000₦60,000 + ₦450,000 + ₦30,000 - ₦50,000 = ₦490,000.
2
Identify Direct Labour and Direct Expenses
Direct Labour = 280,000₦280,000; Direct Expenses = 40,000₦40,000
Direct wages paid to craftsmen directly contribute to product creation (Direct Labour), and royalties paid on production designs represent direct expenses directly traceable to units produced.
3
Calculate Prime Cost
810,000₦810,000
Prime Cost is the sum total of all direct costs: Prime Cost=Direct Materials Consumed+Direct Labour+Direct Expenses=490,000+280,000+40,000=810,000\text{Prime Cost} = \text{Direct Materials Consumed} + \text{Direct Labour} + \text{Direct Expenses} = ₦490,000 + ₦280,000 + ₦40,000 = ₦810,000.

Direct factory labour wages115,000
Royalty paid on apparel designs18,000
Factory supervisor's salary40,000
Factory rent and rates25,000
Depreciation of factory machinery15,000

What is the Prime Cost of production for Apex Apparel Enterprises?

Show answer & explanation

Answer: 382000

Answer

The Prime Cost of production for Apex Apparel Enterprises is ₦382,000.
Prime Cost is the sum of all direct costs incurred in production: Direct Materials Consumed (₦45,000 + ₦230,000 + ₦12,000 - ₦38,000 = ₦249,000), Direct Labour (₦115,000), and Direct Expenses (₦18,000 for royalties). Totaling these yields ₦382,000. Factory overheads such as supervisor salary (₦40,000), factory rent (₦25,000), and machinery depreciation (₦15,000) are indirect manufacturing costs and are excluded from Prime Cost.

Step-by-Step Solution

1
Calculate the cost of raw materials consumed during the period.
₦249,000
Cost of Raw Materials Consumed = Opening Inventory (₦45,000) + Purchases (₦230,000) + Carriage Inwards (₦12,000) - Closing Inventory (₦38,000) = ₦249,000.
2
Identify all direct production costs (Direct Labour and Direct Expenses).
Direct Labour = ₦115,000; Direct Expenses (Royalty) = ₦18,000
Direct costs are expenses directly traceable to the production of goods. Royalties on designs are direct expenses, while factory wages for production workers represent direct labour.
3
Sum Raw Materials Consumed, Direct Labour, and Direct Expenses to arrive at Prime Cost.
₦382,000
Prime Cost = Raw Materials Consumed (₦249,000) + Direct Labour (₦115,000) + Direct Expenses (₦18,000) = ₦382,000. Indirect factory costs (supervisor salary, factory rent, and machinery depreciation) are overheads and excluded.

Key Concept

Prime Cost consists of the sum of direct materials consumed, direct labour, and direct expenses (such as royalties). Indirect factory overheads must be excluded.
Question 7Question

In manufacturing accounting, cost items and inventory adjustments must be categorized accurately to determine the total cost of finished goods. Match each manufacturing cost transaction or inventory item on the left with its corresponding accounting classification and functional purpose on the right.

Click a left item, then click its matching right item

Items

Patent royalty paid per unit of output manufactured
Depreciation of production line plant and machinery
Unfinished units remaining on the factory floor at the end of the accounting period
Sum of Prime Cost and Factory Overheads adjusted for opening and closing Work-in-Progress

Matches

Show answer & explanation

Answer

Patent royalty per unit matches with direct expense forming Prime Cost; Depreciation of factory plant matches with indirect manufacturing expense under Factory Overheads; Unfinished units at period end match with closing Work-in-Progress deducted from manufacturing costs; Sum of Prime Cost and Factory Overheads adjusted for Work-in-Progress matches with Cost of Production transferred to the Trading Account.
Each terminology in manufacturing accounting has a distinct classification based on traceability and function. Patent royalties tied directly to volume are direct expenses contributing to Prime Cost. Factory plant depreciation is an indirect operational cost categorized as Factory Overheads. Closing Work-in-Progress represents incomplete inventory and is deducted from total manufacturing expenses. The resulting grand total represents the Cost of Production, which is credited to the Manufacturing Account and debited to the Trading Account.

Step-by-Step Solution

1
Identify direct cost items traceable directly to production units.
Patent royalty paid per unit is classified as a direct expense and forms part of Prime Cost.
Direct expenses are costs other than raw materials and direct labor that are directly attributable to producing specific units.
2
Identify indirect factory costs incurred within the production facility.
Depreciation of factory machinery is classified under Factory Overheads.
Factory overheads encompass all indirect costs of manufacturing that support production without being directly tied to a specific unit.
3
Analyze the accounting treatment for partially completed inventory.
Unfinished units at period end represent closing Work-in-Progress and are subtracted from cumulative production costs.
Deducting closing Work-in-Progress ensures that costs incurred on incomplete goods are excluded from the period's cost of completed goods.
4
Determine the final output metric of the Manufacturing Account.
Prime Cost + Factory Overheads + Net Work-in-Progress adjustment equals the Cost of Production transferred to the Trading Account.
The primary objective of the Manufacturing Account is to determine the Cost of Production for transfer to the Trading Account to ascertain trading gross profit.

What is the total Prime Cost for the year?

Show answer & explanation

Answer: 880000

Answer

The total Prime Cost for the year is ₦880,000.
Prime Cost represents the aggregate of all direct costs incurred in manufacturing. It includes direct raw materials (purchases of 450,000₦450,000 plus carriage inwards of 30,000=480,000₦30,000 = ₦480,000), direct wages (320,000₦320,000), and direct expenses (80,000₦80,000 for royalties). Summing these direct components yields 480,000+320,000+80,000=880,000₦480,000 + ₦320,000 + ₦80,000 = ₦880,000. Factory supervisor salaries (150,000₦150,000) and factory power/maintenance (200,000₦200,000) are indirect expenses (factory overheads) and are excluded from Prime Cost.

Step-by-Step Solution

1
Calculate Direct Materials Consumed
₦480,000
Carriage inwards on raw materials is a direct cost incurred to bring raw clay into the factory and must be added to raw material purchases.
2
Identify Direct Labour and Direct Expenses
Direct Labour = ₦320,000; Direct Expenses = ₦80,000
Wages of potters directly creating products are direct labour, and royalties on designs are direct expenses.
3
Compute Prime Cost
